24" 201cc Electric Start CVT High-Wheel Mower

High‑power, CVT drive and electric start
9/10
EXPERT SCORE

A premium walk‑behind mower with a 201cc engine, electric start, and CVT drive that adapts to the user's pace. It excels on larger yards and challenging terrain, though the higher weight and price reflect its more robust design.

Pros
Electric start eliminates pull‑cord effort
201cc engine and CVT deliver smooth, adjustable forward speed
Large 24" deck and heavy stamped steel deck for durability
Cons
Heavier and more expensive than compact domestic models
Service and weight can be a drawback for tight storage or single‑person transport

Overview

This Yardmax 24" mower takes a step up in capability with a 201cc OHV engine, electric start, and a continuously variable transmission (CVT) that offers six speed settings. It's intended for homeowners who want professional‑grade convenience and control.

Why it stands out

Electric start for hassle‑free starting and reliable ignition
CVT drive lets users match the mower speed to their walking pace for comfortable mowing
24" cutting deck and heavy gauge stamped steel for better airflow and deck longevity

The CVT is particularly useful on varied terrain: it prevents the mower from bogging in thicker patches and allows the operator to set a comfortable walking rate. The electric start is a tangible convenience for those who dislike pull cords.

Considerations before buying

This model is heavier and more costly, reflecting its more substantial engine and deck. Buyers should plan for adequate storage space and be comfortable with its weight when lifting into a trailer or tight shed. For large yards and frequent, demanding mowing, its durability and features justify the premium.

SENIX 21" Briggs & Stratton Self-Propelled Mower

Dependable Briggs & Stratton power, light frame
8.4/10
EXPERT SCORE

A lightweight, easy‑to‑start 21‑inch mower driven by a Briggs & Stratton 140cc engine that performs well for small to medium lawns. It balances ease of use with strong cutting ability, though some owners reported minor parts or bag capacity limitations.

Pros
Briggs & Stratton 140cc engine with Prime N' Pull start
Lightweight and easy to maneuver
3‑in‑1 cutting and simple 6‑position height adjustment
Cons
Bag capacity may be small for larger yards
Some owners reported isolated early failures or shipping damage

Overview

The SENIX LSSG‑M9 is a 21‑inch self‑propelled mower featuring a Briggs & Stratton 140cc engine and a 3‑in‑1 steel deck. It is aimed at homeowners who want easy starting, a light chassis, and reputable engine provenance without a premium price.

Strengths and practical features

Briggs & Stratton 140cc 4‑cycle engine with Prime N' Pull for reliable starts
21" deck with mulching, bagging, or side discharge options
Six‑position dual‑lever height adjustment and 8"/11" wheels for maneuverability

Users repeatedly point to its strong initial performance and light handlingβ€”particularly attractive for older homeowners or those who prefer an easy‑to‑push machine. The mower comes with a 2‑year limited warranty, which provides some peace of mind.

Limitations and buyer advice

Reports of shipping damage and occasional parts issues exist, so buyers should inspect the unit upon delivery and register the warranty. The included bagger is useful for HOA compliance but can fill quickly on larger properties; consider switching to mulching for bigger jobs.

21" PowerSmart B&S Self-Propelled Mower

Balanced midpriced mower with B&S reliability
8.2/10
EXPERT SCORE

Offers a practical mix of Briggs & Stratton power, a 21‑inch steel deck, and useful 3‑in‑1 clipping options. It performs well for everyday residential use though long‑term mechanical reliability varies across owner reports.

Pros
Briggs & Stratton 140cc engineβ€”smooth starting and performance
Large rear wheels and rear‑wheel drive for traction
Solid 21" coverage reduces mowing time
Cons
Some reports of early drive or plastic component failures
Self‑propel drive can be abrupt for first‑time users

Overview

This PowerSmart mower couples a 21‑inch cutting deck with a 140cc Briggs & Stratton engine and a rear‑wheel self‑propel system. It targets homeowners who want a dependable midprice gas mower with flexible clipping management.

Notable features

Briggs & Stratton 140cc engine with consistent startup behavior
3‑in‑1 bag/mulch/rear discharge and a 1.4‑bushel collection bag
Six cutting heights and 10" rear wheels for confident traction

The unit is easy to assemble and gets most yards cut quickly. The rear‑drive self‑propel helps on inclines, and the single‑lever height change simplifies transitions between seasonal lawn looks.

Limitations and buyer guidance

While many users have dependable seasons of use, several reviewers experienced issues with the self‑propel drive or mounting plastics. Routine inspection of fasteners and prompt warranty registration are recommended. For modest residential use, it presents a reliable balance between cost and capability.

22" PowerSmart B&S Self-Propelled Mower

Reliable Briggs & Stratton power and versatility
8/10
EXPERT SCORE

A solid 22‑inch mower built around a Briggs & Stratton engine that balances power and ease of use. It starts easily, handles thicker grass well, and the self‑propel system reduces fatigue, though some users reported quality control and assembly issues.

Pros
Briggs & Stratton 150cc engine with ReadyStart
Generous 22" cutting width for efficient mowing
3‑in‑1 clipping options and decent grass bag capacity
Cons
Occasional manufacturing/assembly faults reported by owners
Self‑propel speed can be brisk for some users

Overview

This PowerSmart model pairs a 22‑inch deck with a USA‑made Briggs & Stratton EX625 150cc engine and ReadyStart technology. The combination aims to deliver reliable starting, strong cutting performance, and a user‑friendly self‑propelled system for yards up to medium‑large size.

Features that matter

Briggs & Stratton EX625 150cc engine for trusted power and easier starting
Rear‑wheel drive self‑propel for improved traction on grades
3‑in‑1 mulching, bagging, or rear discharge and six cutting heights

Owners commonly praise its cutting ability and how quickly it covers ground thanks to the 22‑inch deck. The ReadyStart reduces frustrating pull‑cord effort, and the self‑propel system is strong enough to pull rather than just assist.

Practical insights and limitations

Quality‑control reports varyβ€”some users received complete, trouble‑free machines while others noted missing hardware or early mechanical problems. The self‑propel system can feel fast at first; taking a short practice pass helps adjust to the pace. For those who want the confidence of a B&S engine at a midprice point, it represents a sensible choice, but buyers should inspect assembly and register the warranty promptly.

21" 170cc Self-Propelled 3-in-1 Mower

Powerful 170cc for medium and large yards
7.6/10
EXPERT SCORE

A capable 21-inch self‑propelled mower that delivers strong cutting power and useful 3‑in‑1 versatility. It trims quickly and handles uneven ground well, though long‑term durability and plastic components are potential concerns.

Pros
Strong 170cc 4‑stroke engine with dependable starting
3‑in‑1 cutting (mulch/side discharge/rear bag)
High‑wheel design improves maneuverability on slopes
Cons
Some fit-and-finish and plastic part reliability concerns
Replacement parts and warranty support can be inconsistent

Overview

This 21‑inch, 3‑in‑1 self‑propelled mower is built around a 170cc 4‑stroke OHV gas engine and a steel deck, aimed at homeowners with medium to large lawns. It offers mulching, side discharge, and a rear bag option so users can adapt to different lawn conditions and HOA rules.

Key features and benefits

170cc 4‑stroke OHV engine for consistent power and reliable starting
21‑inch cutting deck that balances coverage and maneuverability
Six cutting heights (1.5"–3.9") and a foldable handle for compact storage

These features make it a good match for yards with thicker grass or occasional uneven terrain. The large rear wheels help the self‑propel system handle slight inclines without excessive user effort.

Practical insights and limitations

Users will appreciate the immediate cutting performance and the convenience of the 3‑in‑1 system, but several owner reports call out build‑quality issues over timeβ€”loose screws, plastic tabs breaking, and problems with the height lever. For buyers who prioritize initial value and cutting power, this mower competes well; those seeking long service life or dealer support may want to consider a higher‑tier brand.

Who should buy it

It suits homeowners who want a powerful, budget‑minded gas mower that gets the job done quickly and offers flexible clipping management. Buyers comfortable with occasional DIY fixes and vigilant maintenance will be happiest with this model.

Strong 170cc engine and practical 3‑in‑1 design
7.2/10
EXPERT SCORE

A straightforward 21‑inch mower with a 170cc OHV engine that delivers consistent cutting and a variety of clipping options. It offers good value for the price, though some owners reported shipping damage and early mechanical issues.

Pros
170cc engine with forced air cooling for heavy loads
1.4‑bushel grass catcher and six height settings
Foldable handle and easy assembly for quick setup
Cons
Plastic wheels and shipping damage reported by some buyers
Mixed reliability reports after the warranty period

Overview

This 21" self‑propelled mower combines a 170cc OHV engine with forced air cooling, a 21‑inch steel deck, and a 3‑in‑1 clipping system. It is targeted at homeowners who want a straightforward gas mower for routine yard work.

Useful features

High‑performance 170cc engine designed for tougher grass and longer run times
Multiple clipping options (mulch/side discharge/rear bag) and 6 cutting heights
Foldable handle for compact storage and a 1.4‑bushel grass catcher for reduced stops

Owners commonly praise the starting ease and cutting effectiveness on regular lawns. The forced air cooling helps prevent overheating under heavy workloads and higher ambient temperatures.

Limitations and buyer suggestions

Some buyers experienced shipping damage or early failures; thorough inspection at delivery and prompt registration of any warranty are advisable. The plastic wheels and some trim parts can show wear sooner than heavier‑duty competitors, so routine checks and occasional part replacement may be required over the product's life.

21" 170cc Self-Propelled Steel Deck Mower

Big engine in a budget package
7/10
EXPERT SCORE

Delivers strong initial cutting performance with a 170cc OHV engine and useful 3‑in‑1 capabilities. Long‑term durability is mixedβ€”buyers report both straightforward, trouble‑free starts and issues with plastic components and drive reliability.

Pros
Powerful 170cc engine for aggressive cutting
Large 21" steel deck reduces passes
Foldable handle and 1.4‑bushel catcher for convenience
Cons
Inconsistent build quality reported by multiple owners
Height lever and plastic fasteners can loosen over time

Overview

21" steel deck and 6‑position height adjustment for flexible mowing
1.4‑bushel grass catcher and foldable handle for easier storage and cleanup

Practical benefits include fewer passes across a medium‑to‑large yard and the ability to mulch or collect clippings depending on preference. The rear‑wheel self‑propel system reduces effort on slopes and longer lawns.

Limitations and buyer tips

Several reviews note early failures tied to plastic parts, loose screws, or self‑propel drive issuesβ€”this makes thorough on‑arrival inspection and proper break‑in important. Customers who value warranty support or who expect heavy daily use may prefer a unit from a mainstream OEM with a dealer network.

20" 141cc Self-Propelled Push Mower

Compact, easy storage, simple to operate
6.8/10
EXPERT SCORE

A lightweight 20‑inch mower with a 141cc 4‑stroke engine suited for small to medium yards. It starts easy and is simple to store, but build quality and ambiguous height specs may concern buyers with rough terrain.

Pros
Lightweight and easy to assemble out of the box
50L grass tank reduces emptying frequency
Foldable ergonomic handle for compact storage
Cons
Somewhat vague or inconsistent height range reporting
Lower overall durability compared with premium models

Overview

This 20‑inch self‑propelled mower centers on a 141cc 4‑stroke engine and a compact footprint designed for easy storage. It targets buyers with small yards who want a balance between power and convenience.

Key attributes

141cc 4‑stroke engine with reduced noise and vibration
20" blade and a 50L grass tank for fewer interruptions
Large PVC‑wrapped wheels to handle moderate unevenness and a foldable handle

The mower starts easily for most owners and is praised for its immediate usability right out of the box. Its size makes it convenient for garages and sheds with limited space.

Practical considerations

The model is better suited to homeowners whose lawns are relatively even and maintained; heavier duty tasks or frequent rough mowing will stress its components. As with most value‑priced mowers, buyers should expect to perform minor maintenance and keep an eye on fasteners and wheel wear over time.


Final Thoughts

For large or uneven yards where power and a smooth ride matter, the 24" 201cc Electric Start CVT High-Wheel Mower is the clear pick. It pairs a big 201cc engine with an electric start and a CVT drive that adapts to walking pace. It excels on slopes, thick grass, and properties where reducing fatigue matters most β€” ideal for owners who want a premium, heavy-duty walk-behind that gets the job done fast.

For small-to-medium lawns and those who prioritize ease of use and value, the SENIX 21" Briggs & Stratton Self-Propelled Mower earns the recommendation. It’s lightweight, easy to start, and offers dependable Briggs & Stratton power in a compact package. It’s best for suburban lots, tight corners, and people who want a reliable, fuss-free mower without paying for unnecessary heft.


FAQ

Is a self-propelled mower worth the extra money?

For most homeowners it is. A self-propelled system reduces fatigue and keeps pace steady, which matters on bigger lawns, slopes, or when grass is thick. If the yard is tiny and flat, a simple push mower saves money and storage space.

How should they choose between a 21", 22", and 24" deck?

Pick a 24" deck to cut more grass per pass on large yards (faster work). A 21"–22" deck is nimbler for yards with obstacles, tight corners, or narrow gates. Bigger decks are slightly heavier and may be harder to maneuver in cramped spaces.

What advantage does CVT drive give over a fixed-speed self-propel?

CVT (continuously variable transmission) automatically matches the mower’s speed to the operator’s walking pace. That reduces pushback and strain on the operator and drivetrain, especially on slopes and rough terrain. It’s a premium convenience on stronger models like the 24" 201cc CVT mower.

How often should they perform maintenance?

Basic maintenance every season: change the oil, clean or replace the air filter, sharpen or replace the blade, and check the spark plug. Inspect belts, cables, and the drive system annually. Frequent use or dusty conditions may require more frequent attention.

Mulch, bag, or side-discharge β€” which to choose?

Mulching returns clippings as nutrients and keeps the lawn tidy without bags. Bagging is best for tall, wet grass or if clippings need to be removed. Side-discharge is simplest for heavy growth when clogging is a concern. Pick based on grass length, local yard rules, and a preference for lawn appearance.

Any quick tips for storage and winterizing?

Run the tank dry or add a fuel stabilizer before long storage. Change the oil and clean the deck to prevent corrosion. Store in a dry, covered spot and remove the battery (or keep the electric-start battery on a tender) for winter. Remove the blade or secure it safely for maintenance.

Are there climbing or slope limits to worry about?

Yes. Self-propelled mowers help on gentle slopes, but steep inclines still require caution. The heavier 24" high-wheel model handles uneven terrain better due to larger wheels and stronger drive. On very steep terrain, a riding mower, string trimmer, or professional service is safer.

How to tell a good bargain from a false economy?

Look past low price alone. Check engine brand (Briggs & Stratton is a reliable sign), build materials (steel deck vs. mostly plastic), and drive system quality. A slightly pricier mower with a proven engine and solid drive will often cost less over time than a cheaper model that needs repairs.

  1. Quick question: is electric start worth the added cost and weight? Thinking of the 24″ electric start vs the 141cc 20″ foldable model for convenience.

    • Electric start minimizes hassle, especially for those who dislike pull cords or have mobility concerns. If your yard is small and storage is tight, the foldable 20″ might be better despite manual start.

    • If you only mow a tiny yard once a week, I’d pick the lighter 20″ β€” saves space and is cheaper. But if you have slopes or dense grass, electric start with a bigger engine is worth it.

  2. Long post because I wanted to be thorough:
    I purchased the 21-Inch 3-in-1 with the 170cc engine. First few mows were great, cut clean and handled bumps well. Then about 6 months in I had a wheel wobble and one of the plastics cracked where the catcher attaches. Customer service was slow and the replacement part took weeks.

    If you’re buying one of the mid-range 170cc models, be prepared for decent performance out of the box but maybe some QC issues later. Still cheaper than a pro-grade mower, but set aside time/parts budget for small repairs.

    • Good ideas β€” I ended up using a local shop too and it was way faster. Cost me about $45 for labor and parts vs months waiting.

    • You might try a local small engine shop β€” they often have quicker turnaround for parts and repairs than online sellers.

    • Sorry to hear that, Ethan. Those 170cc models do offer good power but, as you noted, some buyers report plastic parts failing. Keeping a basic hardware kit and checking fasteners quarterly can help avoid surprises.

    • Same here β€” had a cracked bracket after one season. I reinforced it with a metal plate and it’s been fine since. Not ideal but cheaper than waiting for OEM parts.

  3. Mixed feelings. I like that many of these mowers are affordable and powerful (170cc looks tempting), but the recurring theme of plastic components and shipping damage worries me. Any maintenance tips to extend lifespan?

    • Totally valid concern. Regular maintenance: change oil as recommended, clean/replace air filter, check/replace spark plug annually, tighten fasteners, and inspect plastic parts for cracks. Also consider pre-delivery inspection if buying online β€” record unboxing in case you need a claim.

    • I keep an extra set of belts and a spare blade. Saved me once when the drive belt frayed β€” had me back mowing in a morning instead of waiting for parts.

  4. I bought the 24 in. 201cc Electric Start Select PACE model last spring and it’s a beast. Electric start is pure luxury compared to pull-starts, and the CVT really makes mowing big slopes less of a workout.

    Only downside: it’s heavier than my old mower so I needed a ramp to get it into the shed. But overall worth the higher price for the performance.

    • Thanks for sharing, Mark β€” glad the CVT made a difference for you. If you have a steep slope, make sure to regularly check belt tension; CVT systems can slip if the belt wears.

    • Good tip about the ramp β€” I built a small plywood ramp and it made life so much easier. Also: a trick I learned is to keep gas stabilized if you store it over winter.

    • How’s the mulching on that model? I’m tired of bagging and my yard gets patchy if clippings sit.

  5. I’m torn between the PowerSmart 21-Inch and the PowerSmart 22-Inch. Practically the same price where I live. Does the 22″ noticeably handle thicker grass better, or is it just marketing?

    • Both are similar in build; the 22″ paired with the 150cc B&S tends to give a bit more torque for thicker grass. If your lawn is mostly normal turf, the 21″ is probably sufficient and a touch easier to maneuver.

    • I have the 22″ β€” the extra inch does help a bit on wider swaths, and the 150cc engine felt stronger on tall/weedy spots. Not a night-and-day difference though.

  6. Oh great, another self-propelled mower so it can do half the work while I sip iced tea. πŸ˜‚
    On a serious note: does anyone find the self-propel mechanism too aggressive on inclines? I don’t want it jerking forward.

    • You can usually manage it by starting at a lower speed and letting the mower set the pace. If it’s jerky, the drive belt or cable might need adjustment.

    • Haha, iced tea is mandatory. The aggressiveness varies by model β€” rear-wheel drive units can be more assertive on inclines. Look for a model with adjustable drive engagement so you can dial it back.

  7. I picked the 20″ 141cc mower because storage is an issue (apartment homeowner). It starts easily and the foldable handle is a life-saver. Not for rough terrain, but perfect for flat small yards. πŸ‘

  8. Nice roundup. The CVT and electric start badge on the 24-inch model clearly put it in a different class (9/10 makes sense). But I wish there were more long-term reliability stats β€” some PowerSmart units look great on paper but reviews mention QC issues.

    Also, anyone tried to retrofit a larger catcher on the B&S models? I’m always annoyed at hopping off to empty the bag every few minutes.

    • If you want reduced stops, consider mulching blades and leaving clippings as long as your lawn tolerates it β€” less bagging required.

    • I’ve seen belly-mounted catchers that give more volume but they reduce turning ease. Trade-offs everywhere lol.

    • Good observation, Emily. We prioritized measured performance and usability in the roundup, but long-term reliability varies β€” we flagged models with mixed owner reports. Aftermarket catchers can work if the mounting points match, but it’s often a bit of DIY.

    • I swapped to a universal 3-bag system on an older Briggs mower β€” more capacity but adds drag and slightly changes balance. Works if you use it occasionally.
